Eustace?

"Even a traitor may mend, I know one who did" (this one is easy).

Sorry, that one was Aravis. (She went on to say that she was sorry before she found out he was a prince.)

Edmund. 🙂

"Prepare the blue fire."

Ah yes, of course!

The hag.

"Weren't we always told she was a worse enemy than the Telmarines?"

I'm pretty sure it was the werewolf... one of them, anyway. 🙂

Caspian?

"Can you see me?"

Iiiiiiiiiii'm guessssssing Lucy, in LB?

"There's something sticking in my back."

Yep.

I'm pretty sure that was one of the Four in the wardrobe... Susan?

"It wasn't luck. It was him."

Peter, actually.

Shasta?

"Would you have a little fencing match with me?"

Aw, man. I thought maybe Su said it and then Peter mentioned wet and cold.

Yep.

Er... Tirian? *doesn't think that's right*

Edmund to DLF ... while he was still Trumpkin?

"One of the poets has said, that application to business is the mother of prosperity while ...."

Oh, right, duh, Ariel....

Arsheesh?

"They are too noble for that."

Yep, either he or Ahoshta, but first of all he.

Someone before a very great ordeal. Since "they", I guess it is not about Aslan's sacrifice, but somewhere in LB. Jill?

Nope, that was spoken by Miraz in the PC movie. Glozelle had suggested that Edmund, Glenstorm, and Wimbleweather had come to surrender, and Miraz said they were too noble for that.

"It has lifted the latch."

Oh, the movie.

Someone in LB again? Except it wasn't the first time.

No, sorry. 'twas Aslan speaking to Rabadash about his impending doom.

"What a magnificent puzzle you are."

Jill to Puzzle?

(Yes, "your doom is at the door" and next "it has lifted the hatch").
